<h2>Navigating the Diagram</h2>


<p>On the left of the screen is the diagram displaying the flow of students between majors. 
There are several (rectangles) nodes labeled with majors. The size of each node corresponds 
to the number of students in that major. Every arrow represents the flow of students from one 
major to another. The width of the arrow corresponds to the number of students moving from the 
source major to the destination major.</p>


<p><b>To navigate:</b></p>
<ul>
  <li>Zoom in and out with the mouse wheel</li>
  <li>To pan, click and drag on the white background</li>
  <li>To move a node, click on it and drag</li>
</ul>
